RESUMO
INTRODUCTION: Neurofibromatosis type 1 (NF1) is a progressive multisystem disorder following an autosomal dominant inheritance pattern that presents with multiple neurological manifestations. METHODS: We reviewed medical histories of patients with NF1 followed up at our hospital's paediatric neurology department from May 1990 to 31 December 2018. We collected data on neurological symptoms. RESULTS: A total of 128 patients with NF1 were identified. Mean age (SD) at NF1 diagnosis was 4.43 (3.38) years (range, 0.5-14.5 years). There was a slight female predominance (53.1%). Macrocephaly (head circumference over 2 SDs above average for age) was present in 37.5% of cases. Attention-deficit/hyperactivity disorder was recorded in 28.9% of patients (37): combined type in 20 patients, predominantly inattentive in 15, and predominantly impulsive/hyperactive in 2. Other manifestations included headache (18.6%), cognitive impairment (7.8%), motor deficit (6.2%), and epilepsy (4.68%). Brain MRI was performed in 85 patients, revealing T2-weighted hyperintensities in the basal ganglia and/or cerebellum in 60 patients (70.5%), Chiari malformation type 1 in 4 cases, and arachnoid cysts in 3. Optic nerve gliomas were identified by MRI in 22 patients (25.8%). Other MRI findings included plexiform neurofibromas (9.3%) and central nervous system gliomas (3.1%). CONCLUSIONS: The neurological manifestations identified in our sample are consistent with those reported in the literature. Effective transfer strategies from paediatric neurology departments and subsequent clinical follow-up by adult neurology departments are needed to prevent loss to follow-up in adulthood.

RESUMO
INTRODUCTION: Acute cerebellitis is a rare inflammatory disease with a highly variable clinical course that ranges from benign self-limiting symptoms to a fulminant presentation associated with a high risk of death due to compression of the posterior fossa, acute hydrocephalus, and intracranial hypertension. METHODS: We reviewed clinical, laboratory, and radiological findings from children diagnosed with acute cerebellitis between May 2007 and November 2016. We analysed treatments and clinical and radiological progression. RESULTS: Nine children met the diagnostic criteria for cerebellitis. Headache, vomiting, and drowsiness were the most frequent initial symptoms; ataxia, dysarthria, and dysmetria were the most common cerebellar signs. Cerebellitis was diagnosed with magnetic resonance imaging, which revealed cerebellar involvement (unilateral or bilateral); computerised tomography images either were normal or showed indirect signs such as triventricular hydrocephalus due to extrinsic compression of the aqueduct of Sylvius. Corticosteroids were the most commonly used treatment (6 patients). One patient required surgery due to triventricular hydrocephalus. Eight patients recovered completely, whereas the ninth displayed neurological sequelae. CONCLUSIONS: Cerebellitis is a medical and surgical emergency; diagnosis requires a high level of suspicion and an emergency brain magnetic resonance imaging study. It is a clinical-radiological syndrome characterised by acute or subacute encephalopathy with intracranial hypertension and cerebellar syndrome associated with T2-weighted and FLAIR hyperintensities in the cerebellar cortex (unilaterally or bilaterally) and possible triventricular dilatation. Treatment is based on high-dose corticosteroids and may require external ventricular drain placement and decompressive surgery.

INTRODUCTION: Patients with neurofibromatosis type 1 (NF1) have a high predisposition to develop attention-deficit disorder. The aim of this study is to determine the prevalence of NF1 patients with attention-deficit/hyperactivity disorder (ADHD) diagnosis attending our Child Neurology Department. We assess patient adherence and medical treatment outcomes. PATIENTS AND METHODS: Identification of patients with NF1 being followed up from December 31 2015 to June 31 2017 with ADHD diagnosis. Clinical and treatment data were collected. RESULTS: 56 patients with NF1 were enrolled in the study with a mean age of 9.83 ± 4.17 years. 23 patients (41%) were diagnosed with ADHD, mean age at ADHD diagnosis of 7.53 ± 2.46 years. School-age children with ADHD represented 48.8% of cases. All but one of the children received treatment, mean duration of treatment was 3.85 ± 3.04 years. 19 out of 22 patients (86%) continue medical treatment. Positive effects were reported by eleven patients with a moderate response in eight patients. CONCLUSIONS: Prevalence of ADHD in patients with NF1 is high. Early diagnosis and treatment of ADHD in patients with NF1 is highlighted by this study. Our study reveals good patient adherence and medical treatment outcomes in most patients.
TITLE: Neurofibromatosis tipo 1 y trastorno por deficit de atencion. Nuestra experiencia actual.Introduccion. Los pacientes con neurofibromatosis de tipo 1 (NF1) tienen una gran predisposicion a desarrollar deficit de atencion. El objetivo del estudio es determinar los pacientes controlados en nuestra seccion de neuropediatria con NF1 y diagnostico de trastorno por deficit de atencion/hiperactividad (TDAH), valorando la adhesion y respuesta al tratamiento. Pacientes y metodos. Se identifica a los pacientes afectos de NF1 que siguen controlados entre el 31 de diciembre de 2015 y el 31 de junio de 2017, y de ellos, los que presentan diagnostico de TDAH, revisando datos clinicos y de tratamiento. Resultados. Se ha controlado a 56 pacientes afectos de NF1, con una edad media de 9,83 ± 4,17 años. De ellos, 23 (41%) presentan diagnostico clinico de TDAH, con una edad media de 7,53 ± 2,46 años en el momento del diagnostico. El 48,8% de los niños en edad escolar esta afecto de TDAH. Todos los pacientes menos uno recibieron tratamiento con estimulantes, con un tiempo medio de tratamiento de 3,85 ± 3,04 años. Continuan con el tratamiento 19 pacientes de los 22 tratados (86%). Once casos refieren una clara mejoria, y ocho, una mejoria moderada. Conclusiones. El TDAH es muy prevalente en niños con NF1. Se destaca la importancia de la identificacion y el tratamiento del TDAH en niños afectos de NF1. Nuestra revision muestra una buena adhesion al tratamiento con estimulantes, con mantenida buena respuesta en la mayor parte de los casos.
